Nitrogen-doped carbon dots/Fe³⁺-based fluorescent probe for the “off–on” sensing of As(v) in seafood

Abstract

In order to better satisfy the application of the food rapid detection method in the detection of As(Ⅴ) in complex food substrates, we developed a "off-on" fluorescence assay to detect...

Detection of Arsenic(V) by Fluorescence Sensing Based on Chlorin e6-Copper Ion

“…Currently, there are many techniques available for copper and arsenic detection, such as atomic absorption/emission spectrometry (AAS/AES) [ 10 , 11 , 12 ], atomic fluorescence spectroscopy (AFS) [ 13 , 14 ], X-ray fluorescence spectroscopy (XRF) [ 15 , 16 ], inductively coupled plasma–mass spectrometry (ICP–MS) [ 17 , 18 ], electrochemistry [ 19 , 20 , 21 ], ultraviolet–visible absorption spectrometry (UV–Vis)/colorimetry [ 22 , 23 , 24 , 25 ], and fluorescence spectroscopy [ 26 , 27 , 28 , 29 ], etc. These methods have their characteristics and advantages for testing different environmental samples, but the drawbacks of some methods, such as AAS/AES and ICP–MS, which require expensive and large instruments and specialized operators, limit their applications [ 27 , 30 ].…”

A resorufin-based fluorescent probe for hydrazine detection and its application in environmental analysis and bioimaging

“…31–38 In contrast, a fluorescent probe has become an ideal detection method owing to its advantages of convenient operation, high specificity, good sensitivity and real-time monitoring. 39–43 Although some fluorescent probes with great advantages of sensitivity and selectivity have been reported, more efficient, easily synthesized and low-cost probes still need to be developed to achieve highly efficient detection of N 2 H 4 in complex environments and biological samples.…”
